Disclosed are a network access method, a terminal and a non-transitory processor readable medium. According to the method, a terminal scans frequency points to perform network search. The scanned frequency points are added to a first pre-set list. If the terminal fails in registration under a current Public Land Mobile Network (PLMN), the frequency points stored in the first pre-set list are searched in a next PLMN registration process so as to perform network registration.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A network access method, comprising: scanning, by a terminal, frequency points of supported bands to perform network search; adding the scanned frequency points to a first pre-set list; and in case that the terminal fails in registration under a current Public Land Mobile Network (PLMN), searching for the frequency points stored in the first pre-set list in a next PLMN registration process so as to perform network registration; the method further comprising: before scanning the frequency points of the supported bands, searching for frequency points stored in a historical registration list, the historical registration list comprising registered frequency points; and in case of failure in searching for the frequency points stored in the historical registration list, scanning the frequency points of the supported bands.
2. The method according to claim 1 , after searching for the frequency points stored in the first pre-set list so as to perform network registration, further comprising: in case of successful network registration, adding successfully-registered frequency points to the historical registration list.
3. The method according to claim 2 , before adding the successfully-registered frequency points to the historical registration list, further comprising: acquiring a current geographic position of the terminal; and establishing a mapping relation between the geographic position and the frequency points; and wherein adding the successfully-registered frequency points to the historical registration list comprises: storing the mapping relation between the geographic position and the frequency points to the historical registration list.
4. The method according to claim 1 , after searching for the frequency points stored in the first pre-set list so as to perform network registration, further comprising: in case that network registration fails, scanning frequency points of the supported bands; adding the scanned frequency points to a second pre-set list; and in case that the terminal fails in registration under the next PLMN, performing network search in a subsequent PLMN registration process according to the frequency points recorded in the second pre-set list and the historical registration list.
5. The method according to claim 4 , wherein the operation of adding the scanned frequency points to the second pre-set list comprises: adding the scanned frequency points to the first pre-set list so as to form the second pre-set list.
6. The method according to claim 4 , wherein the operation of adding the scanned frequency points to the second pre-set list comprises: replacing frequency points in the first pre-set list with the scanned frequency points so as to form the second pre-set list.
7. A terminal, comprising: a processor; and a memory for storing instructions executable by the processor; wherein the processor is configured to: scan frequency points of supported bands when it is detected that the terminal performs network search; add the scanned frequency points to a first pre-set list; and search for, in case that the terminal fails in registration under a current Public Land Mobile Network (PLMN), the frequency points stored in the first pre-set list in a next PLMN registration process so as to perform network registration; wherein the processor is further configured to: search for, when it is detected that the terminal performs network search, frequency points stored in a historical registration list, the historical registration list comprising registered frequency points; and scan frequency points of the supported bands in case of failure in searching for the frequency points stored in the historical registration list.
8. The terminal according to 7 , wherein the processor is further configured to add, in case that network registration succeeds, successfully-registered frequency points to the historical registration list.
9. The terminal according to claim 8 , wherein the processor is further configured to: acquire a current geographic position of the terminal; establish a mapping relation between the geographic position and the frequency points; and store the mapping relation between the geographic position and the frequency points to the historical registration list.
10. The terminal according to claim 7 , wherein the processor is further configured to: scan frequency points of the supported bands in case that network registration fails; add scanned frequency points to a second pre-set list; and perform, in case that the terminal fails in registration under the next PLMN, network search in a subsequent PLMN registration process according to the frequency points recorded in the second pre-set list and the historical registration list.
11. The terminal according to claim 10 , wherein the operation of adding the scanned frequency points to the second pre-set list comprises: adding the scanned frequency points to the first pre-set list so as to form the second pre-set list.
12. The terminal according to claim 10 , wherein the operation of adding the scanned frequency points to the second pre-set list comprises: replacing frequency points in the first pre-set list with the scanned frequency points so as to form the second pre-set list.
13. A non-transitory processor readable medium having processor readable instructions stored therein which, when executed, cause the processor to implement a network access method, the method comprising: scanning, by a terminal, frequency points of supported bands to perform network search; adding the scanned frequency points to a first pre-set list; and in case that the terminal fails in registration under a current Public Land Mobile Network (PLMN), searching for the frequency points stored in the first pre-set list in a next PLMN registration process so as to perform network registration; the method further comprising: before scanning the frequency points of the supported bands, searching for frequency points stored in a historical registration list the historical registration list comprising registered frequency points; and in case of failure in searching for the frequency points stored in the historical registration list, scanning the frequency points of the supported bands.
